Definitions

  • the invention pertains generally to a pipette for a pipette system.
  • the invention is directed to a pipette for the handling of a syringe and includes jaw chucks which are adjustably arranged with respect to a plunger receptacle which is pivotally mounted on a plunger-gripping device.
  • the syringe is received in the jaw chucks in manner such that the plunger head is in marginal contact with the jaw chucks, the jaw chucks being laterally engageable on the plunger head A upon the insertion of the syringe.
  • the engaging movement of the jaw chucks on the plunger head is regulated in a manner such that, with respect to a surface of the plunger head, the engaging movement has a substantially tangential component.
  • German Patent DE 43 41 229 C1 discloses a pipette system in which a pipette-operated syringe can be axially inserted into the pipette, or, respectively, removed from the pipette.
  • the affixing of the cylinder and plunger of the syringe is made using radially adjustable cylinder-gripping and plunger-gripping levers.
  • the cylinder-gripping lever and the plunger-gripping lever are elastically forced into their gripping position and can be brought into a releasing position against the elastic force.
  • the invention also includes an actuating element on the pipette housing is used which is hand-operated against the elastic force.
  • German Patent DE 29 26 691 C2 discloses a pipette system having syringes that can be axially inserted, but are complicated regarding the design of the cylinder-gripping device and the plunger-gripping device. Pipettes having a more simplistic construction have syringes that can be radially inserted into and removed from the pipette. The present invention is based upon such a pipette.
  • the cylinder-gripping device has a radially accessible and permanently mounted on the pipette housing, and is designed as a flange-like ring with a U-shaped top view having a cantilever spring found vertically above it.
  • This cantilever spring supports the fastening section of the syringe cylinder, which is designed as a circular, projecting flange, after radial insertion.
  • the plunger head of the syringe plunger which juts upward from the cylinder, is lead laterally into a plunger receptacle on the plunger-gripping device simultaneously with the insertion of the cylinder flange.
  • the plunger receptacle is formed by two flanking jaw chucks which together form a U-shape and which grip the plunger head from the side and clamp it tight during the insertion of the syringe.
  • An actuating device is mounted on the plunger-positioning device, and is a part of the plunger-gripping device of the plunger-positioning device.
  • the actuating device is a hinged, clamping component that is opened upwardly for the insertion of the syringe and swung down for the final fixation of the plunger head between the jaw chucks. In the down-swing, the jaw chucks, which are already firmly on the plunger head anyway due to their own elastic force, are additionally pressed against the plunger head.
  • the conventional pipette system has an axially working clamp spring which forms such an insertion bevel.
  • its elastic force must be very high in order to achieve an axial movement of the plunger in the pushed-in position despite the clamping force of the already clampingly-engaged jaw chucks.
  • each jaw chuck is provided with an edging, and particularly with a serrated edge.
  • the edging is pressed into the material of the plunger head from the side, especially when dealing with a serrated edge, so that, in respect to the substantial axial forces which are transferred from the plunger-positioning device to the plunger head during operation, not only a friction joint between jaw chucks and plunger head results, but also, to a certain extent, a positive or form joint.
  • the actuating device designed as a hinged cover, for the plunger-gripping device must have a hand-operated element in order for it to be moved.
  • This hand-operated element is disturbing during the operation of a hand-held pipette because it is, necessarily, axially pushed together with the plunger-positioning device in the pipette housing.
  • a corresponding path must therefore be kept free for insertion into the pipette housing.
  • the hand operation collides with the hand holding the pipette. Consequently, problems occur in the case of an ergonomically useful design of the pipette in which the user s hand wraps fully around the pipette housing.
  • the object of the invention is to overcome the aforementioned difficulties for a pipette in which a syringe is radially inserted.
  • the pipette includes jaw chucks that are placed to the side of the plunger head of the syringe, and have little, if no, effect during the insertion of the syringe, and are engaged on the plunger head of the syringe only after a successful insertion of the syringe.
  • the more sensitive plunger head can be inserted into the plunger receptacle practically without the use of large amounts of force.
  • the axial pre-fixation of the plunger head is excluded so that in case of an emergency, the plunger, should it extend too far beyond the end of the cylinder, can be pushed downward even if the syringe is still in place.
  • This can also occur automatically, for example, with an insertion bevel on the closed end of the plunger receptacle of the plunger-gripping device opposite the open end of the pipette housing.
  • it is possible to omit the hinged cover as an actuating device for the plunger-gripping device on the movable plunger-positioning device in the case of a corresponding design of a pipette according to the invention. More so, a fixed activating device can be relatively easily implemented for the plunger-gripping device.
  • the force necessary for forming an adequate, form-locking connection of the jaw chucks on the plunger head is small since an engaging or positioning movement of the jaw chucks is regulated in a manner such that it has a substantially tangential component with respect to the surface of the plunger head.
  • the jaw chucks are provided with a serrated edge so that the production of the necessary, form-locking connection for the application of substantial axial traction results not only by convertibly pressing the serrated edge into the plunger head with very high forces, but also by cutting into the material of the plunger head following the tangential movement.
  • the engaging movement of the jaw chuck can be created by a hand operation of the actuating device.
  • the actuating device is only used for the application of force in the beginning and for later forcing the jaw chucks apart. Therefore, it must be ready for use only for plungers which are entirely or mostly inserted into the cylinder.
  • the actuating device can be removed from the movable plunger-positioning device and can be permanently arranged on the pipette housing with all the advantages for the manageability of the pipette according to the invention.
  • FIG. 1 is a perspective view of a pipette system made of a pipette according to the invention and a syringe mounted on it, ready for use;
  • FIG. 2 is a perspective view of the pipette system having an open syringe receptacle
  • FIG. 3 is a perspective view of the pipette with the syringe being unclamped
  • FIG. 4 is an enlarged perspective view of the area of the syringe receptacle with the housing partially opened;
  • FIG. 5 is an enlarged elevational view of a plunger-gripping device of a pipette according to the invention.
  • FIG. 6 is an elevational view of an actuating device for the plunger-gripping device in which the jaw chucks of the plunger-gripping device are engaged on the plunger head;
  • FIG. 7 is a sectional view of the actuating device with the jaw chucks of the plunger-gripping device being forced apart against the elastic force.
  • FIG. 1 shows a perspective view of a pipette system comprising a pipette 1 and a syringe 2 , the pipette including a gripping mold 3 and a motor actuator 4 .
  • the pipette 1 is a motor-actuated repetitive pipette
  • the teaching of the invention is not limited to a motor-actuated pipette but can also be used for various types of hand-operated or motor-actuated pipettes having an inserted syringe.
  • FIG. 1 and FIG. 4 illustrate a syringe 2 which is inserted into the pipette 1 , and which is normally available as a replacement part, and includes a cylinder 5 with a fastening section 6 , designed here as a flange, as well as a plunger 7 . Only the plunger head 8 of the plunger can be seen in the inserted state, extending beyond the end of the cylinder 5 .
  • the pipette I itself includes a pipette housing 9 , in which an axially movable plunger-positioning device 10 is arranged.
  • the plunger-positioning device 10 is moved by a motor in a motor-actuated pipette 1 or, in a hand-operated pipette, by step mechanics, which works, for example, using pawl and rack.
  • a radially accessible cylinder gripping device 11 is fixedly mounted on the pipette housing 9 .
  • the cylinder gripping device 11 is designed simply as a U-shaped flange-like rim on the pipette housing 9 , on which the fastening section 6 of the cylinder 5 , which is designed as a circular flange, is positioned. This is tensionally affixed to the rim by a cantilever spring 12 which is also indicated in FIG. 4.
  • a plunger-gripping device 13 for the plunger head 8 of a syringe 2 which is radially accessible and movably mounted with the plunger-positioning device 10 is provided as is an actuating device 14 for said plunger-gripping device 13 .
  • FIGS. 3, 4 and 5 illustrate a position in which the syringe 2 is inserted into jaw chucks 16 of the pipette 1 , the jaw chucks 16 being laterally mounted in the plunger receptacle 15 of the plunger-gripping device 13 .
  • the plunger-gripping device 13 grips the plunger head 8 of the syringe 2 with the jaw chucks 16 and holds the plunger head 8 , clamping it laterally so that considerable axial force can be transmitted from the plunger-positioning device 10 to the plunger 7 .
  • the jaw chucks 16 are provided with an edge, preferably a serrated edge 17 .
  • Each jaw chuck 16 includes a total of six serrated edges 17 arranged above one another.
  • the jaw chucks 16 are adjustably mounted in relation to the plunger receptacle 15 , preferably pivotably mounted on the plunger-gripping device 13 . With opened jaw chucks 16 , the syringe 2 is insertable with the plunger head 8 only marginally contacting the jaw chucks 16 and, upon the insertion of the syringe 2 , the jaw chucks 16 are then engageable on the plunger head 8 .
  • FIG. 4 of the drawings illustrates an insertion bevel 23 for the plunger head 8 is arranged on the closed end of the plunger receptacle 15 opposite the open end of the pipette housing 9 .
  • the plunger head 8 is forcefully brought into position during syringe 2 insertion, in which the plunger 7 is completely pushed into the cylinder 5 .
  • the insertion bevel 23 for the plunger head 8 can also be designed as an axially operative compression spring or can comprise such an axially operative compression spring.
  • FIG. 5 shows jaw chucks 16 pivotably disposed on shafts 18 preferably having pivotably disposed serrated edges 17 designed as cutting rollers.
  • the engaging movement on the plunger head 8 or respectively, the surface of the plunger head 8 by the jaw chucks 16 is regulated so that it has a substantially tangential component.
  • This is, hereby, implemented in that the shafts 18 for the jaw chucks 16 are found laterally displaced to the plunger receptacle 15 in the plunger-gripping device 13 .
  • the end position of the engaging movement of the jaw chucks 16 on the plunger head 8 lies directly before or directly after dead center.
  • a definition of dead center is the point in which the central axis of the serrated edge 17 of the jaw chucks 16 lies exactly on the connecting line of the central axis of the plunger head 8 with the shaft 18 of the jaw chuck 16 .
  • FIG. 5 shows an end position of the engaging movement of the jaw chucks 16 which lies slightly before dead center.
  • An adequately long cut line of the serrated edge 17 is invariably striven for as is a secure fixation of the plunger head 8 between the jaw chucks 16 .
  • a position slightly after dead center is acceptable in certain cases.
  • the pipette 1 can also be provided such that the engaging movement of the jaw chucks 16 is created by the hand-operation of the actuating device 14 .
  • FIG. 5 also shows to the left of the two-armed levers, which form the jaw chucks 16 , the engager heads 21 of the jaw chucks 16 . These run along the guide pieces 20 on the inside of the actuating device 14 , forming the shutter in the represented embodiment.
  • the actuating device 14 may also be conventionally arranged on the plunger-gripping device 13 , it will present the same disadvantages explained in the general part of the description.
  • the above-mentioned concept with the engaging movement of the jaw chucks 16 by elastic force allows, however, that as implemented in the embodiment, the actuating device 14 for the plunger-gripping device 13 is mounted on the pipette housing 9 . It is, thus, not moveable with the plunger-positioning, device 10 in the pipette housing 9 , but is permanently arranged on the pipette housing 9 .
  • the actuating device 14 arranged on the pipette housing 9 is designed as a closure for the plunger receptacle 15 .
  • the actuating device 14 is designed as shutter in the represented embodiment. Of course, designs such as a hinged cover, turning lock, or similar are possible. As illustrated in FIG. 1, the shutter that forms the actuating device 14 pushed downward into the closed position, while FIGS. 2, 3 , and 4 show the shutter pushed upward. In this position, the actuating device 14 gives access to the plunger receptacle 15 , while it closes the plunger receptacle 15 in the position shown in FIG. 1 .
  • the represented and preferred embodiment shown in so far, is a construction in which the actuating device 14 releases the jaw chucks 16 when the plunger receptacle 15 is closed and, when the plunger receptacle 15 is opened, opens them against elastic force.
  • the plunger head 8 In the closed position, as shown in FIG. 1, the plunger head 8 can be moved up and down securely coupled by means of the plunger-positioning device 10 .
  • the position of the actuating device 14 represented in FIGS. 2, 3 and 4 is such that the jaw chucks 16 of the plunger-gripping device 13 are forced apart against the force of the cantilever springs 12 by means of the actuating device 14 so that the plunger head 8 is released. This corresponds to the releasing of the plunger receptacle 15 in this position, so that the syringe 2 can be completely separated from the pipette 1 .
  • the actuating device 14 has a guide piece 20 for the engager heads 21 of the jaw chucks 16 , wherein the guide piece 20 is wider on the lower, open end and tapers upwardly.
  • FIG. 6 shows the position of the engager heads 21 in relation to the guide piece 20 , which corresponds to the position of the of the jaw chucks 16 in FIG. 5, i.e. the position having an affixed plunger head 8 .
  • FIG. 7 shows a position in which the shutter, which forms the actuating device 14 , has just begun to be pushed upward into the position shown in FIGS. 2, 3 and 4 .
